I switched from Sprionolactone to Valsartan with my doctor's permission because I hated the restricted diet on Sprionolactone. I was first on 40 mg/day of Valsartan and ate whatever I liked, which includes bananas, lots of dark leafy greens, all sorts of fruit both fresh and dried, etc.. Basically a healthy diet! Well he upped my dosage to 80 mg/day because 40 mg wasn't getting my BP low enough. And immediately I started having horrible, painful muscle cramps in my feet, legs, hands, every night shortly after taking Valsartan. I read about it and that's a symptom of overload of potassium in your system (and can lead to cardiac arrest!!!!!)! I feel as if I can't win! Take BP med but eat a terrible diet of white bread/rice, applesauce and meat with very little healthy greens and fruits! Anyone else have this issue??
